Original application filed December 29, 1922, Serial No. 609,580.

To all whom it may concern:

v Be it known that 1, WILLIAM F. HELMOND, a citizen of the UnitedStates, residing in Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements inTypewriting Machines, of which the following is a specification. V

This invention relates to continuous billing machines, and isillustrated in connec tion with a bookkeeping machine of theUnderwood-I-Ianson type.

When fan-fold mechanism or the like is applied to a bookkeeping machineof the type referred to, the webs must be guided above the usualhousings of the sets of denominational jacks, which makes it diflicultsufliciently to straighten the webs as they extend under the raisedplaten, to permit the carbons to be freely drawn back by the usualcarbon-carriage. Provision is made of means for swinging thedisplaceable platen to an elevated position about an axis more remotefrom the. platen than the axis of the platen-driving pinionabout whichthe platen has been swung in previous machines.- This enables the platento be raised to a greater height, and hence the webs may be straightenedout, even though they are arranged at a high elevation above the addingmechanism at the rear of the machine.

The rear frame-extension of the usual con tinuous billing machine forsupporting the rear carriage-extension adds considerably to the bulk ofthe machine, making it of an inconvenient shape to store or ship. Thisis emphasized in the case of a bookkeeping machine. A feature of theinvention is the provision of a rearwardly-extending bracket, forsupporting the rear carriage-extension, pivoted at its lower end to thesupporting stand of the machine, and capable of being swung down out ofthe waywhen not in use.

The supporting bracket may include side bars connected to each other bycrossrods, the bars being pivotally mounted at their lower ends tothemachinc stand. The up-, per ends are secured to a cross rail, whichserves as atrack for the rear extension of the carriage. For holding thebracket in its operative position means, such as rods, may be provided,said rods having ,one end screwed fast to the machine frame and the thean ac used to th brack t.

Other features inafter appear.

In the accompanying drawings,

Figure 1 IS, a sectional side elevation of a portion of a bookkeepingmachine having the present improvements applied thereto.

Figure 2 is a fragmentary side elevation, showing the supporting frame,with the carriage-extension-supporting bracket swung to loweredposition. 7

Figure 3 is a rear elevation of the machine.

In a bookkeeping machine of the Underwood-Hanson type, a typewriter 11,having a frame 12, rests on a casing 13 of a com puter, which iscontrolled by the numeral keys of the typewriter, and the computercasing13 rests on a stand, comprising a top 14: and supporting posts or legs15.

The typewriter 11 comprises a platen 16 mounted on a platen-axle 17,which is rotatably supported in a traveling carriage 18. The carriage 18is supported at its rear on a rail 19 fixed on the typewriter-frame 12.Provision is made of brackets 20, attached to the rear of thetypewriter-frame 12, at each side thereof, and carrying at their upperends a bar 21, on which may be supported one or more sets ofdenominational jacks 22 and a housing 23 for each set of such jacks. Atthe rear of each housing 23 a casing 24 for the usual thrust-rods (notshown) extends downwardly to the rear of the con puter-casing 13 and isattached thereto.

and advantages will here- The carriage 18 is provided at its rear withbrackets 25 extending rearwardly and outwardly, and havingupwardly-cxtending ends, in which are mounted a rod 26, along which adenomination-selector 27 may be moved, and a notched rod 28 having itsnotches at letter-space distances, the denomination-selector being heldin adjusted positions by engagement of a tooth 29 thereon in the notchesof the rod 28. When the carriage 18 .is traveling through a computingzone, a tappet 30, carried by the denomination selector 27, engagessuccessively the for ward ends of the denominational jacks 22 andselects the. denominations in which digits are to be ndexed.

, carriage-cxtension $6 at its gencri l, similar to tha disclosed in thepat cut to Richard M. Becker, No. 1,296,351, granted iiarch '-l. 1919.

Inasmuch as the present intention con templa es the use in abooicl-tceping; machine oi the features of a co nuons billing machine,the axle 17 of "in platen 1b is journaled in the ends 7-11 of aplaten-displaci11g trame said ends being: QXtCllt ed forwardly and upwaally, and being piyc-ted by such extended portions upon stub-shafts 31),mounted on the frame. of the carriage 18 at the front oi, andcoi'isiderably above, the normal position of the plat n-axl 17. Theplaten-axle 17 is provided its ends with gears 3%, which mesh with broadpinions which, in turn, mesh with gears 37 similar to the gears 3i andfixed on tne inner ends of stub-shafts 3S journaled in the frame oi thecarriage 1S. .Vhen the webs. indica er in general by 40, are to bestraightened under the platen to permit the \it-hd 'awal oi theinterleaved carbon-sheets in the usual manner, the platen 16 is swungupwardly about the shafts 33 to the position shown in Figure 1, the websthen being crawn tor ward and gaged by means of the usual gage l1,adjustable on the gage-bar 12, mounted on a front paper-table 43 whichforms part of the platen-displacing frame 32. Since the displacing frame32 is not swung about the axis of the stub-shafts (not shown), on whichthe pinions 35 are mounted, it will be apparent that the gears 3% willbe carried out of mesh with the pinions S5 in the course of thedisplacing movement. In order to insure reengagement so that the platenmay be returned to its normal, lowered position, without opposition, theteeth of both the gears 8i and pinions are made with sharp points.Yielding abutments or steps ail of rubber or other suitable material aremounted on the carriage 18 to be engaged by stops s t on theplaten-displacing frame 32 for limiting the outward swinging mo' mentthereof.

At the rear of the machine, )rovision is made of a carbon-carrier 4:5,mounted for moyement toward and from the platen upon a rearcarriage-extension or table 1 6 comprising a front member 4.? secured byscrews to bracl s -19 extending rearwardly from the carr 5e 18. a rearmember 50 and a plurality ot connect ng mcu'ibers having on the uppersides thcrcoi' rails with each one oi which eo-operate grooved rol s 5mounted on the baseplate .511: of the carhim-carriage to. 'Thecarbon-carriane 4-5 may be moved to the rear by a handle i in the usualmanner. This handle may be corrugated to increase its rigidity, as shownin Figure 1. To support and guide the rear 1 or end, pr n'ision made ofa guide-rail 6 mounted on a. rear bracket 57 and extending 'i'a'ralleluideail 19. Each of the meml v 23 1 1 H 1 1 1 J 1 01 has an angle-plateab artaciieo LO 1t, uming a downwardly-cxtending portion, and each plate58 carries which rules upon the rail 56.

to the a roller 1.0 bracket 5:. upon which the rail at is mounted, con:n' ses two upwardly and rearwardly inclin .1 bars (1'2, pi olaliymounted at their lower ends in n a shalt 3 carried by lugs ($1 on thetop it frame. The bars (E2 are other by a cross car 535 connected to thetypewr t 66, which are threaded into the typewriterlrame at theirforward ends, and which receive in threaded sockets at their rear endsscrews 67 to secure them to the bars 62. lYhen it desired to reduce thesize ol? the machine, for shipping or for other purposes. the rearcarriage-extension 5 .6 may be dis connected from the brackets t9 by renoying the screws, and may then be slid oil? the guide-rail 56. Thesupporting rods 00 ot the brackets 57 may be quickly disconnected tromthe machine-frame 12 and from the bracket 5T, to permit the b 'acket tobe swung down about the shaft 63 to the position indicated. in Figure2'.

Variations may be resorted to within the scope of the inyention, andportions oi? the in'iproyements may be used without others.
